QSFP-DD Transceiver,200G,LR4,10km

Description
F-tone Networks’s FTQD-2H-LR4xx 200GE QSFP-DD Optical Transceiver modules are designed for using in 200Gigabit Ethernet 10km links over SMF single-mode fiber. They are compliant with the QSFP-DD MSA and with IEEE 802.3cn 200GBASE-LR4 specification. Digital diagnostics functions are available via the I2C interface as specified by CMIS V4.0. These modules can convert 8 channels of 25Gbps (NRZ) electrical input data to 4 channels of 50Gbps (PAM4) optical signal, and also can convert 4 channels of 50Gbps (PAM4) optical signal to 8 channels of 25Gbps (NRZ) electrical output data. And these modules incorporate F-tone Networks Technologies proven circuit and EML technology to provide reliable long life, high performance, and consistent service.
